	* SignedXml.cs: Return an empty (not null) KeyInfo by default and
	don't throw a CryptographicException in CheckSignature (both NET_2_0).
	* KeyInfoRetrievalMethod.cs: Don't include an empty URI attribute
	in the XML output for NET_2_0.
	* XmlDsigXPathTransform.cs: Throw an XPathException in NET_2_0 if no
	xpath expression has been supplied to the transform.
